Specification of Letters Patent. Application filed September 10, 1912. Serial No. 719,640.

Patented Feb. 3, 1914.

To all reborn it may concern Be it known that I, SILVIO COCANARI, technologist, a subject of the King of the Belgians, and resident of 152 hausse dAnvers, Vieux-Dieu, Belgium, have 'invented certain new and useful Improvements in and Relating to Kinematographic Films, of which the following is a specification,

My present invention relates to kinematographic films and has for its object to provide an improved method of and devices for'enabling films, the width ofwhich is reduced to the width of the prints, and films of any desired width less than the usual films, to be used in ordinary kinemat'ographic machines.

In contradistinction -to arrangements heretofore known, my present invention provides means, whereby t e film is not directly engaged by the pins of the feed-rollers of but through the agency of a supporting strip "the longitudinal rims of which are' provided with perforations in tended to be engaged by the pins of said suitable apertures corresponding to the size of the pictures of the film.

A further object' of my invention is to provide means, whereby the film and supporting strip are temporarily connected toon each other when-passing in front. of t e lens of the kinematographic apparatus.

In carrying the invention into practical effect, I preferably form the supporting strip of an endless belt, which is moved through the apparatus in the usual way and detachably connected to. the film near the lens of saidapparatus, so that the film is caused to pass infront of the lens as usual, whereupon the film is again disengaged from the supporting belt and wound upon the receiving roller 1n the usualway.

It will be seen that my present invention provides means, whereby many objections inherent to the old arrangements may be completely avoided.

The usual films provided withlateral per-.

- forationsand actuated directly by the pinrollers of the kinematographicapparatus, do not enable films of any desired width to be used in the same apparatus, and the printed surface of said films is comparatlvely small, as comparatively large rims must be left on either side for the perforations. In eontradistinction to this old arrangement, my present invention enables."

filmsof i ifierent width to be used'in th'e same apparatus, that is, the width of "the films may bereduced to the width of the printed pictures, whereby a great deal of material, may be saved. Furthermore, my invention enables old films, the perforated rims of which are worn out-or injured, to

be used again, said rims being merely cut away to this end, so as toreduce the width of the films to the width of the pictures.

I may also usefilms of any other width, provided that. the apertures of the supportingbelt correspond to the size of the pictures. r I will now proceed to describe my invention in detail with reference to the accompanying drawings, wherein:

Flgure'l showsa printed film, the width of which is-reduced to 25 mm. and a usual film (in dottedlines) of 35 mm. wide; Fig. 2 shows the front elevation of a portion of the supporting strip; Fig. 3 is a vertical section of same; Fig. 4c is a diagrammatical view of a kinematographic lumiere apparatus, provided-with the endless support ing. belt; Fig. 5 shows a supporting belt for narrow films (20 mm. wide); and Fig. 6 shows a film corresponding to the supporting belt shown in Fig. 5. Fig. 7 is a diagrammatical view of .a Pathe apparatus provided with the endless belt.

As shown in Fig. 1, the printed film 11 is made of a width A-B, which is equal to the width of a picture 8. Arranged below said films is a film of usual width C+D, and this illustration shows clearly the quantity of material which may be saved by using the film 11 instead of the film CD. Arranged between the adjacent pictures of the film 11 a on the plain transverse surfaces 7 are perforations 6. The supporting strip 1, shown in Figs. 2 and 3 is made of the same width as the usual films and has perforations 2 on its longitudinal rims. Said stri 1 is provided with apertures 3, corresponding to the size of thepictures printed on the films to be used in connection with the strip 1. The transverse rims 5 between the adjacent apertures carry projectin pins 4;. intended to engage the correspon ing perforations 6 of the films;

The supporting strip 1, which may be made of sheet steel or any'other suitable material, has its ends preferably connected together to form an endless belt. This endless supporting belt may be arranged-on any ordinary kmematographic apparatus, as shown in Fig. 4 the arrangement being such that the belt passes over a roller 9 andbetween a suitable pressing-device 10 and the lens of the apparatus. Said supporting belt is actuated by the usual operating devices of the apparatus. The film 11 is moved in theusual way from the feed roller over a.

tions 6 of the film, so that .the film is drawn forwardly by the supporting belt. After the latter and the film are moved beyond the lens, the film will be disengaged'from the supporting belt and wound upon the receiving roller in the usual way.

Owing to the use of supporting belts made of strong material such as metal or the like, the apertures or openings of said belts may be made comparatively large, while the transverse solid parts between the adjacent apertures may be made comparatively nar-- row, whereby films with larger pictures than heretofore may be used. Furthermore the provision of supporting belts ofthe kind described enables films of reduced width to be used as shown by way ,of example in Figs. 5 and 6.

The arrangement described -has the following advantages: 1. In ordinary kinematographic machines I may use films, the width of which is utilized totally for printing pictures. 2. I may use printed films of different width in the same a paratus. 3. As the whole surface of t e films is utilized for printing pictures upon the same, the material will be utilized in the best manner. 4. Owing to the use of a strong supporting belt, the film is prevented from bein injured'in contradistinction to the usual lms, whose longitudinal rims are perforated. 5. I may use old injured films, by cutting away the injured perfonosnae rated rims and perforating the plain portions between the adjacent pictures.

What I claim and desire to secure by Letters Patent of the United States is 1. The combination with a kinematographic machine, of a film whose longitudinal rims are not provided with perforations, a suitable supporting device having perforations at the longitudinal rims and corresponding to the pins of the operating rollers of the machine, said supporting de- 76 vice being provided with apertures corresponding to the pictures printed upon the film and means for temporarily connecting the supporting device andthe nlm, substantially as set forth.

2. The combination with a kinemato-' graphic mechine of a film whose longitudinal rims are not provided with perforations,

an endless belt, apertures in said belt corresponding to the pictures printed upon the .85 film, meansfor moving the belt throughthe machine, and means for temporarily connecting the belt and film, substantially as set 'fort 3. The combination with a kinematographic machine, of a film made of the width of the pictures printed upon the same and whose longitudinal rims are not provided with perforations, an endless belt, per forations at the longitudinal rims of the belt and corresponding to therpin-roller's of the machine, apertures in the central portion of said belt and corresponding to the size of the pictures printed upon the film, and means for temporarily connecting the belt and film, substantially as set forth.

4. The combination with a kinematographic machine, of afilm made of the width of the pictures printed upon the same, an endless belt, perforations at the longitudinal 105 rims of said belt and adapted to cooperate with the driving-rollers of the machines, apertures in the endless belt corresponding to the pictures printed upon the'film, means for temporarily connecting the belt and film, and means for firmly pressing the film upon the belt when it is connected with the latter, substantially as set forth.

5. The combination with a kinematographic machine, of a film made of the 115 width of the pictures printed upon the same, perforations between the adjacent pictures of said film, an endless belt, means for moving said belt, through the machine, apertures in the belt corresponding to the 120 pictures of the film, and projectlng pins between said apertures adapted to engage the perforations of the film near the lens of-the machine, substantiall as set forth.

6. The combination wit a kinematographic machine, of a film made of the width of the pictures printed upon the same, perforations between the adjacent pictures of said film, an endless belt, means for moving said belt through the machine, apertures in the belt corresponding to the pictures of the film, projecting pins between said apertures adapted to engage the perforations of the film near the lens of the machine, and means for securely holding said pins in engagement with said perforations when the belt and film are moved together in as set forth.
